A set of scores can be one type of scale or another depending on what the set of scores representsConsider the number of errors made by rats in learning a mazeIf the data represent simply the number of errors then the scores form a ratio scaleThe numbers have all four properties and it makes perfectly good sense to say that if Rat A made 30 errors and Rat B made 15 errors then Rat A made.
After drying in an oven the mass reduces to 16Determine the water content the density of moist soildry density void ratio porosity and degrees of saturationIII A sample of dry soil weights 68gmFind the volume of voids if the total volume of sample is 40ml and the specific gravity of solid is 2.
Aug 03 2019nbsp0183323Keep the container in the oven with the lid removedMaintain the temperature of the oven at 110 177 5176CDry the specimen for a period varying with the type of soil but usually 16 to 24 hoursAfter drying remove the can carefully from the oven using gloves or tongsAllow it to cool to room temperature.
Bank Weight of Soil Same as Max Dry Density Know MoreJan 14 2005 0183 32 85 is a reasonable estimate of bank density to maximum dry density however it is very easy to determine the inplace density of a material excavate a small amount and determine its density again after the bulking associated with excavation.
Bulk density is the weight per unit volume of a soil sampleCalculate the bulk density of a 400 cm3 soil sample that weighs 575 g oven dry weightR b M s V s 575g400cm 3 1Calculate the bulk density of a 400 cm3 soil sample that weighs 600 g and that is 10 moisture.
Jul 06 2020nbsp018332The moisture content has a very strong influence on the mechanical behavior of the soilThe Oven dry method is widely used for the determination of water contentThe loss of weight that happens due to drying results in the measurement of the moisture content of the sampleThe temperature at which the sample is ovendried ranges from 110 o C.

Jun 24 2020nbsp018332If the sponge is placed in an oven at 105186 C it will lose water and therefore lose massSimilarly airdried soils contain waterAirdried sands retain the least water while airdried clays retain the most relative to oven drying.
Sep 27 2020nbsp018332Find the dry unit weight of soil when the unit weight of soil is 12 and the moisture content is 6This implies that γ Unit Weight of Soil 12 w Moisture Content 6γ d γ 1 w γ d 12 1 6 γ d 12 7 γ d 1Therefore the dry unit weight of soil is 1.
The water content of air dry soil will increase and decrease as the relative humidity of the air it is exposed to changesThe uptake of water by oven dry soil is shown in Figure 7Thus determination of water content just before analysis is criticalNormally mass measurements are not made on hot objects.
Soil water content can be measured on a mass or volume basisGravimetric soil water content is the mass of water in the soil measured as the difference between the moist soil and the soil dried at 105176C known as the ovendry weightNote that gravimetric soil water content is expressed per unit mass of ovendried soil.
Sulfur dioxide and butadienes B3 and B2 are to be stripped with nitrogen from the liquid stream as shown in Figure so thabutadiene sulfone BS product will contain less than 0Estimate the flow rate of nitrogen N2 and the number of equilibrium stages requiredAt 70xB0C Kvalues for SO2 B2 B3 and BS are respectively 6.
To be within 1 of the oven dry moisture and is verified at least every 90 daysThe offset factor k shall be used to correct the moisture content reading from the gauge• Moisture content as a percent by mass of dry soil mass to the nearest 01 percent • Dry density to the nearest 0.
Weigh the dish plus the sample and record the weight to the nearest 0And record the weight in the laboratory notebookPlace the sample dish in a drying oven set at 105 177 5176CAllow the sample to remain in the oven overnight 12 to 16 h.
